Correct Answer: D

Rationale: Prinzmetal's angina, also known as variant angina, is characterized by episodes of chest pain that occur at rest and are relieved by nitroglycerin. Patients with Prinzmetal's angina may also have transient ST-segment elevation on an electrocardiogram (ECG) during episodes of chest pain. This is due to coronary artery vasospasm, which causes temporary obstruction of blood flow to the heart muscle. Stable angina typically presents with chest pain on exertion that resolves with rest, while unstable angina and acute myocardial infarction present with chest pain that is not relieved with nitroglycerin and are associated with more severe coronary artery disease.

Correct Answer: A

Rationale: Turning and repositioning the patient every 2 hours is the most effective nursing intervention in preventing pressure ulcers in a patient with a history of stroke and immobility. Pressure ulcers, also known as bedsores, are caused by prolonged pressure on the skin, leading to reduced blood flow and tissue damage. By regularly turning and repositioning the patient, pressure is relieved from specific areas of the body, helping to prevent the development of pressure ulcers. This intervention helps to redistribute pressure, improve blood flow, and reduce the risk of skin breakdown, thus promoting skin integrity in immobile patients.

Correct Answer: D

Rationale: Tipping Claudia's head back slightly helps in reaching the conjunctival sac easily. The conjunctival sac is a small space between the lower eyelid and the eye itself where eye drops are typically administered. Tilting the head back allows for better access to this area, ensuring the eye drops are delivered accurately and effectively into the eye.

Correct Answer: C

Rationale: The correct response would be "Absorption of iron is enhanced with Vitamin C." Iron absorption is increased in the presence of Vitamin C. Therefore, recommending Evelyn to take her iron supplement with a source of Vitamin C such as orange juice or a Vitamin C tablet would optimize the absorption of iron in her body and help prevent maternal anemia more effectively. Taking iron with other vitamins separately, after a full meal, or with milk would not have the same beneficial effect on iron absorption as combining it with Vitamin C.

Correct Answer: C

Rationale: The presence of spindle-shaped cells and psammoma bodies on fine-needle aspiration biopsy is characteristic of follicular thyroid carcinoma. This type of thyroid cancer can present as a thyroid nodule associated with signs of hyperthyroidism due to the release of thyroid hormones from the cancerous thyroid cells. Hashimoto's thyroiditis is an autoimmune condition that typically presents with hypothyroidism, while Graves' disease is another autoimmune disorder that results in hyperthyroidism but is not associated with the presence of spindle-shaped cells and psammoma bodies in this context. Papillary thyroid carcinoma may also present with thyroid nodules, but it is more commonly associated with papillary structures and nuclear features rather than spindle-shaped cells seen in follicular thyroid carcinoma.
